Yongyeon Cave

Even in hot summer, the internal temperature is cool enough to maintain 10 degrees Celsius.

Nice cave, quite attractive, I like it very much.

Oxygen City#Taibai# From the past "carbon transportation high road" to the present "yuntan high road" [666]#Taibai# and the Taibai Mountain, known as the national spirit mountain, is the backbone of the Korean Peninsula ⸺ the center of the white head dry, but also the birthplace of the mother river of South Korea ⸺ the Han River and Luodong River. Taibai is known as the oxygen city, with a clean natural environment, as a plateau city with an average altitude of 600 meters, summer and winter are long, and the snow scenes in Taibai Mountain are particularly intoxicating.

The cave was simple and not overly decorated.
